Object Oriented Database Design Clearly Explained

This book has not taught me anything new. I can not think who the intended audience would be. In the preface the author claims you need to be thoroughly familiar with the relational database model and that you do not need a background in the OO paradigm.

Part one, a hundred pages of theory, explains the OO data model. UML is shortly mentioned, but throughout the rest of the book ER models are used. The quality of some of the models is doubtful, as inheritance seems overvalued. Normal associations, like delegation or other forms, are not mentioned as an alternative. I do not know why this book has OO Database design in the title, because hardly any specifics about this topic can be found in the book.

The equivalent of SQL for OO databases is ODL and OQL, but it is stated 'A discussion of OQL is beyond the scope of this book'. So what is in the scope of the book?

Part two, two hundred pages, consists of three case studies. It contains many pages on useless company descriptions. The OO database design is based on the relational model, copied from the book Relational Database Design by the same author. Some tables are slightly objectified, but this is all that is done. There is no design, just repetitive code listings, of which the book contains no less than hundred pages.

I cannot recommend this book, you better read a good OO introduction and find another source for OO databases.
